There has some confirmation during the stream, they decrease the bonus amount not only from weekly and all the bonus are effete (monthly, base amount and etc). And tables games from stake with the lowest house edge are no longger counted.

The thing is.... you will not be able to wager $10 000 per week without doing it with the original games, so those people that does that, will have almost no weekly or monthly. (Stake want to force people to use all the bonuses they give to players on Slots and Sport betting, where they get the most profit)
But, I also understand their point of view too, they know that if they just made everything limitless, then there would be people who would abuse that, even know people open multi accounts to abuse it when they can, which is sad, so they are sort of right too.
